Automated performance retrieval and automated performance remediation and incident resolution

Abstract

A method for automated retrieval of performance data and incident resolution based on an incident report in a telecommunications carrier network comprising a radio access network. The incident report is delayed relative to the retrieved performance data, and the method includes receiving an incident report based on first data associated with a first cell site, where the first data is associated with a first time; querying the first cell site for performance data of the first cell site responsive to the incident report; receiving performance data from the first cell site responsive to the query, where the performance data is associated with a second time that is later than the first time; and implementing a control response at the first cell site responsive to the received performance data, where the control response is to resolve an incident indicated by the incident report.
